Which nerve in the lumbar plexus is present in only about 10% of the population? a : accessory obturator nerve b : obturator nerve c : genitofemoral nerve d : iliohypogastric nerve e : ilioinguinal nerve

A : accessory obturator nerve

Explanation:

The accessory obturator nerve -found in about ten per cent of the population- is placed medial to the psoas major and anterior to the obturator nerve. It has a small size and emerges from the ventral divisions of the third and fourth lumbar nerves.

The obturator nerve is located on the ventral divisions of the second, third and fourth lumbar nerves in the lumbar plexus; the genitofemoral nerve is placed in the abdomen; the iliohypogastric nerve arises in the lumbar plexus and involves the lateral gluteal area and transverse abdominal muscles; while the ilioinguinal nerve operates from the first lumbar nerve to the iliohypogastric nerve.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

i dont know it at allnow im just getting points at this pint
